UNlTED STATES STANLEY W. HAYES, OF RICHMOND, INDIANA.

DERAIL.

Application filed December 5, 1922. Serial No. 604,982.

To ((77 whom it rmrj/ conccrn Be it known that I, STANLEY lV. Tlinrns United States citizen, residing in Richmond, county of avnc, State of Indiana, have invented the following described Improvements in Derails.

This invention is a hand operated derail having target operating connections constituting a positive lock against operation of the derailinp, member by the target line, but interferintr not at all with detailing-member-initiated movement of the lSRI'FICiJ line unauthorized or accidental operation of the target as by the dropping! of a stone or other weight on the target line being thereby preeluded.

This derail, in common with that of my application of even date herewith Serial No. 604,981, filed December 5. 1922, by virtue of lost motion connections has the characteristic of delivering a hammer blow to said connections in movement of the derailingr member to open or closed position thus insurinn a vigorous completion of the movement of the parts when once started and bv the slammint: 01 the derail block on to the rail dislodging foreisrn material as mud or ice therefrom and positively and nropcrlv seating: or withdrawing the derail block. The connections in the case of both these derails, include an actuator with reference to which the derailimz member is movable sa d actuator and member havin s opposed abutment surfaces two o1 which are in contact at the beginning of the stroke in either d r ction. but separate during the stroke as the derailinc: member acquires mon'ientum, and the other two of which are brought into contact in the striking of the hammer blow.

The type oi derail in wh ch this invention is exemplified and in which it is most sat st'actorilv embodied. is one ha inq a derailinn' member swincinc" oil" and on the rail. and in the derail illustrated the dcrailinor member and the actuator are pivoted eccentricallv with reference to each other. The arrangement and connections are such that .in either extreme position of the dera l hey occupy a si'ibstantiallv dead center osition thus precluding tarrret-line-initiated movement. the lost motion characteristic of the connections nevertheless nerrn ttinc' derailine-member-initiated movement.

Referring to the drawinrrs. F o'urc l is transverse section of the open derail; Fig

ure 2 is a rear elevation corresponding to Figure 1; Figure is a transverse section showing the derailing member just past midposition in its railward movement; Figure 4 is a section transverse to the rail of the closed derail; Figure 5 is a plan view of the open derail, and Figure 6 a detail.

The base of the derail is provided with tront and rear walls 1 andQ, and sidewalls 3 and 4 having lateral spike flanges 5 with strengthening ribs 6. a roof 7 and upstandins; lugs R receiving the hinge pin 9, on which is mounted to swing to and from the rail. the derailinn' member having the derail block proper 10 with hand hold 10 (Fig. 2) and the hinge-pin lugs 11 through which the pin 9 passes. The dot-ailing member has abutment surfaces snitablv rounded and shown as studs 12. 13 which for strength may be connected hv a portion li nakina a double or dumb-bell cam. The derailina member also carries a lug 15 the functions of which will presently appear. This double cam and his 15 nroiect inward from opposed intermediate walls of the derailinc' member spaced to receive without undue sidewise plav the actuator about to be described and which is so termed because, thourrh itself actuated hr the hand operated derailinsr member. it is the primary or actuating member oi the connections. n the structure illustrated. the actuator takes the form of a cranlr 16. the upper part of whi h is located in the space between the sa d walls on the derailincr member and extends therefrom in o and through spacc in the root oi the base. the crank beinn pivoted eccentricallv with reference to the derailine: memher and being so constructed that can move throuc'h the proper angle without interferin! with the hinge pin 9 which is with-inc its path. For this purpose it mav be p ided with a segmental slot 17 of a size to receii e the hin o pin 9 without unnecess rv nlav. the actuator bcinc thus susnended from the said nin but such susnension thou h desirable is not essential. The nreferred form of actuator has a pair of trunnions 18 mounted in vertical slots at each s de of the actuator and confined between the front and rear walls of the slots. the actuator thus beinn free to swing in its own plans but being' prevented from bodily movement transverse or len qthwise of the rail. These slots are formed as parts of the roof'aa by de-' mentum strikes the actuator a hammer blow.
